Apple Music has many wrong album covers after importing itunes library
I have a pretty extensive Itunes library with tons of stuff that's been ripped from cd or vinyl, as well as stuff that's been purchased online, and it's taken years to get all the album covers right. I recently updated my old 2014 Mac Mini to a new Mini and followed instructions to move my library to the new one. It seems that all the music is there, but a good 30% or more of the album covers are wrong, sometimes the right artist wrong cover, sometimes wrong all together. Please tell me there's a way to rectify this without having to do it manually, as there are thousands of albums to be done.
